Go-hashes and cryptography

This is a created article in which the information may have evolved or changed.

In this section, we only give an example of MD5 and an example of SHA1, respectively, corresponding to:
-MD5 algorithm under the Windows platform
-Calculate SHA1

Code:

package mainimport (    "fmt"    "crypto/md5"    "crypto/sha1")func printBytes(x []byte) {    for _, b := range x {        fmt.Printf("%02x ", b)    }    fmt.Println()}/*C:\Go\bin\go.exe run D:\examples\helloworld.go6c d3 55 6d eb 0d a5 4b ca 06 0b 4c 39 47 98 39 aa f4 c6 1d dc c5 e8 a2 da be de 0f 3b 48 2c d9 ae a9 43 4d */func main() {    x := md5.Sum([]byte("Hello, world!"))    printBytes(x[:])    y := sha1.Sum([]byte("hello"))    printBytes(y[:])}
